HiFi Rose RA180 integrated amplifier

HiFi Rose RA180 integrated amplifier
From the Henley Designs press release
Say hello to the otherworldly-looking Hi-Fi Rose RA180. Dr Leonard H. McCoy’s tricorder would likely identify the RA180 as a ‘stereo amplifier’, but this is ‘Stereo Amplifier: The Next Generation’. 
Specifically, the HiFi Rose RA180 is a next generation Gallium Nitride FET Applied Class AD Amplifier. In HiFi Rose’s own words, ‘In terms of power amplifier design, Class D is theoretically a topology that provides a completely linear output at 0% distortion and 100% power efficiency. To achieve the perfect Class D design theory, the switching operation speed and accuracy must be secured. To improve this problem, RA180 implemented a perfect linear output by applying a Gallium Nitride FET instead of a Silicon FET to dramatically improve the Dead Time, which affects switching speed and accuracy, to less than 1/10. The perfect linear output goes beyond the existing Class D limits and creates a natural sound like an analogue amplifier.’
Exclusively distributed in the UK by Henley Audio, HiFi Rose is the brand quickly making a big name for itself in the world of audio, especially with its premium-level streaming products. The arrival of the RA180 integrated amplifier signals a new category for the Korean brand. The RA180 boasts one of the most comprehensive feature-sets of any high-end amplifier, and serves as the ideal partner to its maker’s award winning music streamers. The RA180 is designed to bring to amplification, what the HiFi Rose streaming products bring to digital audio; consolidating connection options that are varied enough to suit any premium audio system, so users can focus on the most important thing – musical enjoyment.

  • Next-generation Class AD (Advanced D) amplifier design with 800W output
